299,792,458 meters per second or 186,282 miles per second in a vacuum. Light slows down in air, more so in water.
The speed of light is 186,000 miles per second (approximately 300,000 kilometers a second).
Light goes about 300,000 kilometers in one second. (in a vacuum)
299,792,458 meters per second or 186,282 miles per second in a vacuum. Light slows down in air, more so in water.
A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles. A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles.
Light anywhere travels about 186,000 miles in one second. It takes light 8 minutes for sunlight to reach Earth.
In a vacuum, light will travel 299,792,458 meters in one second.
If the frequency of the light is 650000000000000 cycles per second, then 650000000000000 waves of this light pass by in one second.
No, that would be a light-second. A light year is the distance light travels in one year, which is 5,865,696,000,000 miles (5.87 trillion miles). Or 946,080,000,000,00 light travel 300,000 km per second
A millionth of a second is one microsecond. It is the length of time a beam of light, traveling about 3 x 108 meters per second, will take to go about 300 meters.
Light doesn't actually go around the Earth; light travels in generally straight lines. But if light DID go around the world, it could go around the world seven times in just less than one second.
Light travels at 300,000 km/sec. (in a vacuum). That is enough to go 7 1/2 times around the Earth in a second (but note that light has a natural tendency to go in a straight line).
About 186,000 miles per second.
